Abstract (en)

[origin: FR2864100A1] Surface-active cationic block copolymers comprising a hydrophilic block derived from monomers with cationic nitrogen atoms and a hydrophobic block derived from diene, vinylaromatic, vinylic and/or (meth)acrylic monomers (optionally hydrogenated) are new. Independent claims are also included for: (1) bituminous composition comprising bitumen and a copolymer as above; (2) producing the bituminous composition in the form of an aqueous emulsion by dissolving the copolymer in an acidic aqueous phase and adding bitumen; (3) bitumen-coated aggregates (especially cold-coated) based on a mixture of aggregates and the bituminous composition; (4) bituminous paving based on the bituminous composition.
